Salmon River Mountains, Idaho

Frank Church-River of No Return Wilderness is the largest designated wilderness area in the contiguous United States.

Many amazing animals live in the Salmon River Mountains, including mountain lions, black bears, lynx, coyote, the powerful mountain goat, wolverines and red foxes

Much of the Salmon River Mountain Range has remained unchanged since the arrival of early European immigrants in 1805.

Wild salmon can swim 1,400km and climb 2,000 vertical metres without eating in order to return to spawning sites in the Salmon River and its tributaries.

In certain places, the Salmon River Canyon is 300 metres deeper than the Grand Canyon.

The Salmon River Mountains contain some of the most important breeding grounds for wild salmon in the contiguous United States.
